COUCH BED.

Application filed March 25, 1921. Serial No. 455,531.

To all whom t may concern.'

Be it known that l, EDWARD TURsroN. a citizen of the United States, resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Couch- Beds, of which` the following is a specification.

This invention relates to improvements in the type of couches that are designed to be converted into beds of substantially greater width than the main or seat portion of the couch, and the object of the invention is to provide a couch having a main or seat section, a back section, and a front section in which,wlien the device is'to be used as a couch, the back section is locked in a nearly upright position the front section being turned down into a substantially vertical position; in which it is necessary to raise the front section before the back section can be turned down; in which, when the three sections are in a horizontal p'osition, the back and front sections are locked against downward movement, andthe back section must be turned up torelease the front section and permit it to be turned down into a vertical position.

The invention consists generally in the constructions and combinations hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure l is a plan 'view of a couch-bed with movable sections turned into a horizontal position, a part of the bed beingbroken away,

Figure 2 is aside elevation of the struc ture shown in Figure l, looking in the direction of the arrow, the movable front and back sections being shown in dotted lines in the positions they occupy when the device is being used as a couch, y

Figure 3 is a detail elevation of a part of the structure shown in Figure 2, looking in the direction of the arrow in said figure.

In the drawings, A represents, as a whole, the main or seat portion of the couch. B represents the back section and C the front section. The main section A is preferably provided with the end rails 2, 2, suitable legs 3, 3, cross bars l and longitudinally extending bars 4a. Suitable braces, such as 6, may also be used to strengthen or stien the main section of the device.

The back section B, consists of a substane of the arms of the frame from points sul stantially over the pivots l to the ends of the arms. The pivots l are located a short distance from the ends of the bars 2, of the main section, and the flanges 5, on the arms of the back section, are adapted to lap over the tops of the bars 2 on the main frame when the back section B is turned down to a horizontal position, as shown in Figure l of the drawings, and as shown by full lines in Figure 2. Theend portions of the anges 5, near the pivots l, with this arrangement, when the back section is turned down to a horizontal posit-ion, rest upon the horizontal parts of t-he bars 2, as shown in Figure l of the drawingaand this engagement forms a ioclr for the back section B, and prevents said back section B from turning down beyond the horizontal position shown by full lines in Figure 2.

The front section C is pivotally connected to the front edge of the main or seat section A, as indicatedin Figures l and 2 of the drawings. As here shown, this front section is secured to the upper portions of plates 7, preferably by suitable rivets 8, and the plates 7 are pivoted to the front or outer ends of the rails of the main section at 9. As herein shown, the plates are of substantially triangular forni, but the shape of the plates is not important and may be varied without deiiarting from my invention.

l prefer to provide the entire frame formed by sections A, B and C with a suitable wire netting or fabric E, preferably provided with the usual tension springs 10. As shown in Figure 1, the edges of this fabric are secured to the frames A, B and C, said fabric permittin the turning of the front and back extensions when it is desired to change the position of the elements of the couch.

The backl section B is provided with forwardly extending lugs or extensions 11, and the lower portion of the triangular plates 7 joining the front section C to the main section B, form downwardly extended lugs 13 substantially at right angles to the plane of the said extension.

, connecting rod or link 12 at each end of The distance between the p-ii'ot point 1 of the back B and the pivot 14%-, connecting the end ot the lugl 11 with the rod 12, is substantially equal to thedistance between the pivot 9, of the liront section C, andthe pivot 15 near the end o1n the iup; 13, to which the end el the link is connected.

lIt will be seen that the lugs 11 to which the links 12 arev connectedy are in line with, or may be said to be in the' saine plane with, the back section B, while the lugs l5,l to which the opposite ends ot the links 12 are connected, project at right angles to the plane ot the tront section C. rlhe result ot this arrangement is that when the sections'B and C' are turned into u' horizontal position,

as shown in Figures 1 and, 2 oit the drawing, the portion oi the bacl: section B engaging the top ot the end portion ot' the rail 2, pre- 'Vents saidback section from being turned down beyond the horizontal position. Then Vthe back section B occupies'the horizontal position, shown by 'full `lines in Figure 2,

the front section C will be in the horizontal position shown by full lines in Figure 2, and said section C will be locked intliis horizontal position.. lt can not nieve down- `Ward'because-the rod or linitll, which noir Figure 2 ot the drawings, until the back section B has been raised, turning' upon its pivots `1 and throwing downward the 4ends of the bars V12 connected'thereto, and moving` the back section B Vtroni the position shown in full lines in Figure 2 to the position shown'in dotted lines in the saine ligure-f. This motionot the' hack section B n'ili, through the a'rn'is or links 12, turn the 'front section C trom the position shown by 'hill lines in Figure 2 tothe position shown by dotted lines in the saine iigruie.

The back'sectionB will nor.' be locked in the position shown in dotted `lines in Figure 2, and thishsection can not beturned .flown into. a horizontal position except by raisins;

the free edge ofthe front section turnin said section upon its pivots-9, and bringing the section from theposition shown in dotted lines lin'y Figure 2 to the `position shown in 'full lines in the saine usure.

I do not limit myself to the details of the `construction h'ereinshoniny and described,

nor do l liinit this invention to use upon a conch-bed. lt is obvious that the invention inay be applied toa chair haiinga seat poi'- tion, and pivoted back and tront'seetions, and I, therefore, include such a. chair strucyture Within the terins ot the specification above said freine to forni seat-back and. "the other section-lowered below saifl,'traiiie,

and links connecting' saidsections one with the other, the connections of said 'links with ,aid Vsections 'preventing the back section troni being lowered until the trout section is i raised,` and preventing the liont section troni being loiifered untiltlie back section is raised.

2. llhe combination, with a couch traina ot front and back sections pivotedthereon and adapte'dto be adjusted to a horizontal position on alevelwith Y, aine tor use as a couch, or one section iised to a po above said traire to torin a seat backend other section lowered l'elowy said traine, said the baci; sectionliaying extensions beyond its pivots in the plane ot the section, si l front section having outsideV the `plane pivotally i connecting;

3. The combination, with a couch traine, of :liront and back sections pivoted to seid traine near the top thereof, and adapted to be adjusted to a horizontal position on a level with the top oil the traine for use as a conch` the back section being,r adapted to be turno-fl up to form a seat-back and the front scf:M tion to be turned down in front of the traine,

theback sections having; extensions beyond its pivotsin the plane oitv thefsection, and the front section having extensions opposite its pivots and substantially at a right angle to theplane ofthe section, and klinks connecting said'extensions, and operating, when the back section is elevated, to vloclr said section in its upright position, and, when -the f tions are horizontal, toilocl; the trontscction in `its horizontal position.

ln Witnessv whereof, l have hereunto set my hand thisv 21st day of March 1921.
